Procedure for the production of a laminated material, whose upper layer has a paper impregnated with an aminoplast resin and surface-modified silica nanoparticles, with the surface modified silica nanoparticles presenting at least one silane on its surface, which carries at least one functional group, the upper layer being joined with a lower layer and / or a support layer, characterized in that a dispersion consisting of surface-modified silica nanoparticles and a dispersing agent on an already impregnated paper is applied for the formation of the upper layer of the laminated material. with an aminoplast resin, at least one of the liquids of the group consisting of water, polar solvents and solutions of a modifying agent being used as dispersing agent. |
